Toward a Rational Design of Conjugated Copolymers with Oxygenated Side Chains for Boosting Thermoelectric Properties

open access: yesAdvanced Energy Materials, EarlyView.
The molecular design strategy that integrates both side chain and backbone engineering in diketopyrrolopyrrole‐based conjugated polymers to identify the optimal balance between doping efficiency and microstructural order is demonstrated. Comprehensive spectroscopic, electrochemical, morphological, and structural characterizations reveal that the ...

Extended Fused Carbazole‐BODIPY, High Brightness NIR Organic Dyes

open access: yesAngewandte Chemie, EarlyView.
Highly fused boron‐dipyrromethene (BODIPY) with a strong donor group has been synthesized, and their photophysical behaviors fully characterized. They exhibit outstanding brightness for fluorophores emitting in the NIR region. Water‐soluble nanoparticles filled with one of these dyes demonstrate high efficiency as the NIR II visualization agent ...

Selective Ion‐Blocking Strategy for Stabilizing Perovskite Tandem Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
A selective ion‐blocking Li─T interlayer is introduced at LiF‐passivated perovskite interfaces to suppress fluorine diffusion while preserving the beneficial interfacial passivation of LiF. This ion‐blocking strategy markedly improves the long‐term operational stability of both single‐junction and monolithic all‐perovskite tandem cells under continuous

Restricting Copper Reconstruction with Ultrathin Polydopamine for Selective and Stable Electrochemical CO2 Reduction Reaction to C2 Products

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
An ultrathin polydopamine coating on copper microcubes mitigates the surface reconstruction during EC‐CO2RR. Copper nanocubes form on the surface of the microcubes in the early stages of the EC‐CO2RR, contributing to suppressed surface reconstruction and sustained Faradaic efficiency for C2 products.

Bright Siren without an Electromagnetic Counterpart Detected by the LISA-Taiji-TianQin Network

open access: yesThe Astrophysical Journal
Gravitational waves (GWs) with electromagnetic counterparts (EMc) offer a novel approach to measure the Hubble constant ( H _0 ), known as bright sirens, enabling H _0 measurements by combining GW-derived distances with EM-derived redshifts.

Copper Contact for Perovskite Solar Cells: Properties, Interfaces, and Scalable Integration

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Copper electrodes, as low‐cost, scalable contacts for perovskite solar cells, offer several advantages over precious metals such as Au and Ag, including performance, cost, deposition methods, and interfacial engineering. Copper (Cu) electrodes are increasingly considered practical, sustainable alternatives to noble‐metal contacts in perovskite solar ...

Integrated Experimental and Theoretical Insights into Defect‐Induced Functionalities of Cobalt Doped NiO for Multifunctional Solar‐Driven Applications

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Rational defect engineering in Co‐doped NiO nanostructures, synthesized via a sustainable green route, enables precise bandgap modulation and defect‐state tailoring. Combined experimental–density functional theory analysis identifies 15% Co doping as the optimal threshold for maximizing photocatalytic degradation, photothermal response, and hydrogen ...

The Effect of Silk on the Stabilization of Labile Enzyme Lipoxygenase

open access: yesAdvanced NanoBiomed Research, EarlyView.
Entrapping lipoxygenase within silk significantly extended its stability from under 24 h to 10 days. Variations in silk molecular weight and freeze‐drying conditions influenced silk properties and enzyme interactions. This stabilization is leveraged to develop a linoleic acid electrochemical biosensor, integrating lipoxygenase with horseradish ...
